    It feels so good to have completed all of this. Never would have believed I'd have gone through a full algebra course so long after leaving school as I've always seen maths as a bit of a blind spot, but I feel so much more confident in going onto more complex maths now.
    I can't thank you enough Prof Dave. You are a hero!

    After the time I've spent on studying your lessons. I think I've gotten addicted with the intro. It's like a ritual that I need to watch first before the lesson starts. 🤣

    I just finished algebra 1 and 2 and geometry this quarantine, (and also astronomy), time to head out to trigo and calculus. thanks a lot prof dave! I've learned a lot and had fun!

    My son is taking statistics got an 81% on a big test last night I’m very proud of him I didn’t think that this would be very applicable in real life but after watching this video I can see I was clearly wrong.

    For someone who has learning disabilities, this is very in-depth, shows a hands-on way of learning, makes it relatable, and goes step by step. It is a great resource.

    13:45 shouldn't it be 45 possibilities? you already have one of the kind of the fourth card on the table, so only three of them are in the deck, or not?

    i got lost when she started splaining the three of a kind cards

    • @RedRahiq
      @RedRahiq 2 месяца назад

      Three of a kind are when you get three cards with different type ( Hearts, Clubs,...) but same number or kind (Ace, 7, Queen,...) and the other cards must be different because if we had a 4th card that matches the first 3 then it is a Four of a kind and not three of a kind. So the 4th card possibity is 52-(3 we got + 1 that matching card)=48 possibilities. If the 5th card matches the 4th then it is a Full house but we want Three of a kind and not a Full house. A Full house is when we have Three cards of the same kind and a pair of the same kind. So the 5th card possibility is 52-(3 we got + 1 that matching + 4 that matches the 4th card)=44 possibilities.
      48x44 all by 2 as we want a combination, not a permutation. Then we multiply 52 by it, get 54912 then divide it again by 2598960 (number of combinations) to find how likely we could get a Three of a kind, which is 0.0211 or 2.11%.

    About the example with the 2 dices there is something I don’t get. Why are for example 3&5 and 2&6, 3&6, 4&5, and 4&6 counted double and 4&4, 5&5 and 6&6 not. This does not make any sense for me.

    Hey guys im so lost with my assignment about probability (including combinations) so
    What if a player is given 2 rounds to pick a color? For example, the player must get a pink and a pink to win a game, a pink and a blue is a loss regardless of the order. Considering that there are 10 overall options 4 pink,3 blue, 2 black and 1 brown
    . 100 trials for example.
    Will I be using combinations with repetition formula (because colors can be repeated)?
    My working out so far:
    Based from the combination with repetition formula -> 11C2 = 55
    Pink and Blue -> 12
    Pink and Black -> 8
    Pink and Brow -> 4
    Blue and Black -> 6
    Blue and Brown -> 3
    Black and Brown -> 2
    Pink, Pink -> 10
    Blue, Blue -> 6
    Black, Black -> 3
    Brown,Brown -> 1
    which all totals to 55, Am I on track or completely off track? or do I use the other formula?
    so for example pink and blue to convert it into percent its going to be
    (12/55) x 100 = 21.81 percent ish of getting it
    or is it going to be
    pink and blue example
    (4/10 x 3/10) X 100 =12 percent of getting it??
    please T^T

    • @matemaatika-math
      @matemaatika-math 4 года назад +1

      For every trial: The total of combinations is 45. Good combinations are the sum of pairs: 6 + 3 + 1 === 10. Probability: 10 / 45 === 2 / 9.
